The Australian Medical Association said the Government must be clear with medical staff.

"We have been told by the Government that they are determined to open the hospital in November. We keep hearing rumours it's going to be a problem," Dr Michael Gannon said.

Hospital delays bring election risk, says analyst

Dr Gannon said he understood the Government was in a difficult position, but it must not risk rushing the project.

"All we ask for is a bit of openness so that we know what is going on," he said.

"The people of WA are also entitled to that certainty about when the services will move to the brand new hospital."

Further delays in the hospital's commissioning would likely push the opening closer to the next state election, due in March 2017.

Analyst Martin Drum said while the Government could use that as an opportunity to earn praise for the hospital, it also carried risk that teething problems would undermine its achievement.

"They are actually better off delaying it [until after the election] and getting all those teething problems sorted out," he said

"The most unfortunate scenario would be if it doesn't get opened at all before the next election, which would be a great shame I am sure for the Government, who put that work in and don't get any of the kudos that comes with that."
